Answer:
Step 3 is incorrect
Step-by-step explanation:
4(-1/2x + 7) + 5x = 15
-2x + 28 + 5x = 15
3x + 28 = 15
3x + 28 - 28 = 15 - 28
3x = -13
Answer:
46
Step-by-step explanation:
The answer is 92. subtract 44 from 136 and you get x = 92
Answer:
Step-by-step explanation:
Compare the equation with y = mx + b where m is slope and b is y intercept
y = (5/4)x - (7/4)
Slope = m = 5/4
In order to solve this we need to get x by itself on one side.
We need o start by adding across the 4 so that we get:
x/3 = -7 + 4 = -3
We then need to multiply both sides by 3 to get a singular x:
x = -3 * 3 = -9
