What is the solution to 7+3x≤8 (3+x) ?

7+3x≤8 (3+x) perform indicated multiplication on right side

7+3x≤24+8x subtract 8x from both sides

7-5x≤24 subtract 7 from both sides

-5x≤17 divide both sides by - 5 (and reverse direction of inequality sign because of multiplication/division by a negative value)

x≥-17/5

x≥ - 3.4

X is greater than or equal to - 3.2
