Answer: x=15
Step-by-step explanation:
3(x-5)+4x=5(x+3)
distribute
3x-15+4x=5x+15
combine like terms
7x-15=5x+15
add the 15 over to the right side
7x=5x+30
minus 5x over
2x=30
divide by 2
x=15
Answer:
x = ±6
Step 1: Write out equation
x² + 7 = 43
Step 2: Subtract 7 on both sides
x² = 36
Step 3: Square root both sides
√x² = √36
-18 and 15
-18 + 15 = -3
-18 x 15 = -270
