Answer:
The first pair shows equivalent expressions.
Step-by-step explanation:
3(x+2), you would have to distribute 3 among x and 2, also known as expanding the expression. So you'd do 3*x + 3*2, which equals 3x+6
The first equation is 3(x+2)=3x+6
Therefore, the first pair shows equivalent expressions.
That's a big one. Take it step by step.
-4x+14+20x= 2(10x-3)
Combine like terms.
16x+14= 20x-6
Add 6 on both sides.
16x+20=20x
Subtract 16x on both sides
20=4x
Divide by 4 into both sides.
x=5
