Answer:
x ≈ 4.3
Step-by-step explanation:
<em><u>Distribute the 4 to (8x - 3) and the 5 to (x - 5), like so:</u></em>
4(8x - 3) - 30x = 5(x - 5)
32x - 12 - 30x = 5x - 25
<u><em>Add like terms (32x and -30x), like so:</em></u>
32x - 30x = 2x
2x - 12 = 5x - 25
<em><u>Subtract 2x from both sides:</u></em>
2x - 12 = 5x - 25
-2x -2x
____________
-12 = 3x - 25
<em><u>Add 25 to both sides:</u></em>
-12 = 3x - 25
+ 25 + 25
____________
13 = 3x
<em><u>Divide both sides by 3:</u></em>
4.3 ≈ x
Answer:
x = 13/3
Step-by-step explanation:
4(8x-3) - 30x = 5(x-5)
Distribute
32x - 12 - 30x = 5x -25
Combine like terms
2x -12 = 5x-25
Subtract 2x from each side
2x-12-2x = 5x-2x -25
-12 = 3x-25
Add 25 to each side
-12+25 = 3x-25+25
13 = 3x
Divide each side by 3
13/3 = x
