Solve for x. 10x – 79 = 2x + 49 x = [?]

Harrizon [31]

Answer:

$x = 16$

Step-by-step explanation:

Step 1: Add 79 to both sides

$10x - 79 + 79 = 2x + 49 + 79$

$10x = 2x + 128$

Step 2: Subtract 2x from both sides

$10x - 2x = 2x - 2x + 128$

$8x = 128$

Step 3: Divide 8 from both sides

$\frac{8x}{8} = \frac{128}{8}$

$x = 16$

Answer: $x = 16$

Answer:

$\large\boxed{x=\dfrac{5}{4},\ y=\dfrac{15}{16}}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}y=\dfrac{3}{4}x&(1)\\\dfrac{5}{2}x+2y=5&(2)\end{array}\right\\\\\text{Substitute}\ (1)\ \text{to}\ (2):\\\\\dfrac{5}{2}x+2\left(\dfrac{3}{4}x\right)=5\\\\\dfrac{5}{2}x+\dfrac{3}{2}x=5\\\\\dfrac{5+3}{2}x=5\\\\\dfrac{8}{2}x=5\\\\4x=5\qquad\text{divide both sides by 4}\\\\x=\dfrac{5}{4}$
