BARSIC [14]

4(x+2)=3(x-2)

Multiply the first bracket by 4

Multiply the second bracket by 3

4x+8=3x-6

Move 3x to the left hand side, whenever moving a number with a letter the sign changes ( positive 3x to negative 3x)

4x-3x+8=3x-3x-6

x+8=-6

Move positive 8 to the right hand side

x+8-8=-6-8

x=-14

Check answer by using substitution method

Use x=-14 into both of the equations

4(-14+2)=3(-14-2)

-56+8=-42-6

-48=-48

If x = 10, find the value of:<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B2%20%7Bx%7D%5E%7B2%7D%28x%20-%205%29%20%7D%7B10x
vesna_86 [32]

Answer:

10

Step-by-step explanation:

\frac{2(10)^2(10-5)}{10(10)}

Square the 10.

\frac{2(100)(10-5)}{10(10)}

Subtract 10 with 5.

\frac{2(100)(5)}{10(10)}

Multiply the numbers in the numerator.

\frac{2(500)}{100}

\frac{1000}{100}

Divide 1000 with 100.

=10
