Answer:

X=3

Step-by-step explanation:

2(4x-3)-t=4+2x

multiply parentheses by 2

8x-6-8=4+2x

Calculate

8x-14=4+2x

Move terms

8x-2x=4+14

Calculate the sum after collecting like terms

6x=18

Divide both sides by 6

Which could be the first step in solving this system of equations by substitution?
Ainat [17]

Answer:

The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)

solve and get

(2.5,17.5)

or x= 2.5 y=17.5

Step-by-step explanation:

The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x

7x-x=15

6x=15

x=2.5

Then we can solve for y

y=7(2.5)

y=17.5
