Q. Solve for x.7x+39≥53 AND 16x+15>31Choose 1 answer:(A) x>1(B) x≥2(C) x≤2D There are no solutions(E) All values of x are solutions
Solve first inequality: Solve the first inequality 7x+39≥53.Subtract 39 from both sides to isolate the term with x.7x+39−39≥53−397x≥14
Isolate term: Divide both sides by to solve for x.\newline\frac{777x}{777} \geq \frac{141414}{777}\newlinex \geq 222
Divide both sides: Solve the second inequality 16x + 15 > 31. Subtract 151515 from both sides to isolate the term with xxx. 16x + 15 - 15 > 31 - 15 16x > 16
Solve second inequality: Divide both sides by 161616 to solve for xxx.\newline
\frac{16x}{16} > \frac{16}{16}
\newlinex > 1
Isolate x term: Combine the solutions of both inequalities to find the common solution set.\newlineFrom the first inequality, we have x≥2x \geq 2x≥2.\newlineFrom the second inequality, we have x > 1.\newlineThe common solution set that satisfies both inequalities is x≥2x \geq 2x≥2.
