Question

solve:
3(2x−5) + 4 = 2x + 19
6x - 15 + 4 = 2x + 19

Explanation:

Step1: Expand left-hand side

$3(2x-5)+4 = 6x - 15 + 4$

Step2: Simplify constants on left

$6x - 15 + 4 = 6x - 11$

Step3: Isolate x terms to left

$6x - 2x = 19 + 11$

Step4: Calculate both sides

$4x = 30$

Step5: Solve for x

$x = \frac{30}{4} = \frac{15}{2}$

Answer:

$x=\frac{15}{2}$ or $x=7.5$
