Question

(3) $\frac{x}{2}+1$(4) $\frac{x}{3}+3=9$(5) $\frac{x}{3}+2=7$(6) $\frac{x}{4}+2=6$(7) $\frac{x}{2}+1=6$(8) $\frac{x}{4}-2=8$(9) $4(x-1)=8$(10) $8(x-3)=24$(11) $3(x+2)=15$(12) $6(x+3)=42$(13) $4(x+3)=24$(14) $7(x+6)=49$

Explanation:

(3) $\frac{x}{2}=1$

Step1: Isolate $x$ via multiplication

Multiply both sides by 2:
$x = 1 \times 2$

(4) $\frac{x}{3}+3=9$

Step1: Subtract 3 from both sides

$\frac{x}{3}=9-3$
$\frac{x}{3}=6$

Step2: Isolate $x$ via multiplication

Multiply both sides by 3:
$x=6 \times 3$

(5) $\frac{x}{3}+2=7$

Step1: Subtract 2 from both sides

$\frac{x}{3}=7-2$
$\frac{x}{3}=5$

Step2: Isolate $x$ via multiplication

Multiply both sides by 3:
$x=5 \times 3$

(6) $\frac{x}{4}+2=6$

Step1: Subtract 2 from both sides

$\frac{x}{4}=6-2$
$\frac{x}{4}=4$

Step2: Isolate $x$ via multiplication

Multiply both sides by 4:
$x=4 \times 4$

Answer:

$x=2$
