Yes, Bobby will have enough money if he saves for 9 weeks. You can find this through either substituting w for 9 in the equation, or solving the equation itself.
Substituting:

Substitute w for 9.

Simplify.

Solve.
255 is greater than 250, so yes, he will have enough money saved.
Solving the equation:

Original Equation

Subtract 30 from both sides.

Divide both sides by 25.

m=9
Step-by-step explanation:
Answer:
x = 1
Step-by-step explanation:
<u>Step 1: Choose one of the equations to solve for y:</u>
x - y + 1 = 0
(-y) / -1 = (-1 - x) / -1
y = 1 + x
<u>Step 2: Plug in y into either equation</u>
3x + 2(1 + x) = 7
3x + 2 + 2x - 2= 7 - 2
5x / 5 = 5 / 5
x = 1
Answer: x = 1
