Answer:
x = 1
Step-by-step explanation:
2x + 3y = 20
2x + 3(10-4x) = 20
2x + 30 - 12x = 20
combine like terms
-10x + 30 = 20
-30 -30
-10x = -10
divide both sides by -10
x = 1
Hope this Helps!!!
3x -x + 8 + 5x - 2 = 10
3x - x + 5x = 10 -8 +2
7x = 4
x = 7/4
Answer:
-7/10
Explanation:
Given the expression

We can rewrite the expression as:

The number line showing the location of the two numbers is attached below. Therefore:
Answer:
lots of multiplying I've noticed
To get y by itself subtract 2x from both sides. The left side becomes 3y=12-2x. Then divide by 3 on both sides to get y by itself. Which you get y=4-(2/3)x
