Step-by-step explanation:
<u>Step 1: Define</u>
7x = 2(x - 50)
<u>Step 2: Solve for </u><em><u>x</u></em>
Distribute 2: 7x = 2x - 100 Isolate <em>x </em>term: 5x = -100 Isolate <em>x</em>: x = -20
Answer:
x= -20
Step-by-step explanation:
So the first thing you would want to do is multiply 2 on both x and -50. After that you will end up with 7x = 2x - 100. Then you will need to subtract x on both sides getting 5x = -100. Finally you will need to divide 5 on both sides getting x = -20
