Solve y=3x-7 and 4x+3y=18 by substitution

x = 3 and y = 2

Step-by-step explanation:

y = 3x - 7

substituting for y in 4x + 3y = 18, we will have

4x + 3(3x -7) = 18

4x + 9x - 21 = 18

13x = 18 + 21

13x = 39

x = 3

Substituting for x in y = 3x -7, we have

y = 3(3) - 7

y = 9 - 7

y = 2

5.5

step-by-step explanation:

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
