First rewrite the equation:8x + 4y = -56
Step 1: Add -4y to both sides.
<span><span><span>8x + </span>4y + <span>−4y </span></span>= −<span>56 + <span>−4y</span></span></span><span><span>8x = −<span>4y −</span></span>56</span>
Step 2: Divide both sides by 8.
<span><span><span><span><span>8x/8 </span></span></span></span>= <span><span><span><span><span>−<span>4y </span></span>−56</span>8</span></span>/8</span></span><span>
Answer:
x=<span><span><span><span><span>−1/</span>2</span></span> y=</span>−<span>7</span></span></span>
Answer:
6^2
Step-by-step explanation:
it is a division between two power with the same base, so we have to subtract the exponents
6^(6-4) = 6^2
The correct answer of

if x=4 is 272.
to solve the equation if x equals 4, you must substitute the x of the 4.

then solve by order of operations.
solve what is inside the parentheses first

then do the multiplication of the factors

then the final step, adding, to get the solution of 272
