How do i solve this equation
dedylja [7]
The first step to solving this is to multiply both sides of the equation by 3
8 + 10y = 9y - 12
now move the variable to the left side and change its sign
8 + 10y - 9y = -12
move the constant to the right side and change its sign
10y - 9y = -12 - 8
collect the like terms for y
y = -12 - 8                  (it equals 1 when you subtract 10 from 9 which is the same is simply saying "y")
calculate the difference on the other side of the equals sign
y = -20
this means that the correct answer to your question is -20.
let me know if you have any further questions

I dont understand how to do this
Airida [17]

The statement EF=2.GF (Option A) and the statement

\frac{\sqrt{3} }{2} .EF=GE (Option C) are true for the ΔEFG.

<h3>What are trigonometric ratios?</h3>

The six trigonometric ratios of a right-angle triangle are Sin, Cos, Tan, Cosec, Sec and Cot. Trigonometric ratios are used to measure the sides of the right triangle.

Given that in ΔEFG, m∠E=30°, m∠F=60° and m∠G=90°.

Wow, sin 30°=\frac{GF}{EF}

⇒\frac{1}{2} =\frac{GF}{EF}

⇒EF=2.GF

and sin 60°=\frac{GE}{EF}

⇒\frac{\sqrt{3} }{2} =\frac{GE}{EF}

⇒\frac{\sqrt{3} }{2} .EF=GE

Therefore, the statement EF=2.GF (Option A) and the statement \frac{\sqrt{3} }{2} .EF=GE (Option C) are true for the ΔEFG.
