= 4x - 11
x is the input, y is the output.
So if you want to know what input is needed to get an output of 10, set y to 10 and solve for x:
10 = 4x - 11
21 = 4x
x = 21/4
Answer:
X=7
Step-by-step explanation:
STEP 1: Simplify both sides of the equation
7x + -10 + 2x =39 + 2x
(7x + 2x) + (-10) = 2x + 39 (combine like terms)
9x -10 = 2x + 39
step 2: Subtract 2x from both sides
9x -10 - 2x = 2x + 39 - 2x
7x - 10 =39
Step 3: Add 10 to both sides.
7x - 10 + 10 = 39 + 10
7x = 49
Step 4: Divide both sides by 7.
7x/ 7 = 49/7 <u> x=7</u>
