Solve system with substitution

julia and willie each improved their yard by planting rose bushes and shrubs. they bought their supplies from the same store. julia spent $136 on 11 rose bushes and 4 shrubs. willie spent $148 on 2 rose bushes and 11 shrubs. find the cost of one rose bush and the cost of on shrub.

The cost of 1 Rose Bush= $ 8

The cost of 1 Shrub =  $12.

Step-by-step explanation:

The cost of 11 rose bushes and 4 shrubs =  $136

The cost of 2 rose bushes and 11 shrubs =  $148

Let the cost of one rose bush =  $x

and the cost of one shrub  =  $ y

Now, according to the question:

11 x + 4 y = 136

and 2 x + 11 y  = 148

From (1), we get that 11x  = 136 - 4y

or,

Substitute this value of x in equation (2), we get

or,

or, 113 y = 1356

or, y = 1356/113 = 12

⇒ y = 12, So

or, x  =8 and  y = 12 is the solution of the above system.

Hence, the cost of 1 rose bush  = $x = $8

and  The cost of 1 shrub = $ y = $12.

b. x- 48 =120

step-by-step explanation:

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
