Solve the linear system below using substitution y=2x+2

4x+y=-10

fill the blanks with the solution

( -2, -2)

Step-by-step explanation:

plug in 2x+2 for y

4x + 2x + 2 = -10

6x +2 = -10

6x = -12

x=-2

y= 2(-2)+2

y = -4+2

y= -2

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
