Been stressing out on this can anyone help

43+(x-7)=90

43+(x-7)-43=90-43

(x-7)=46

x-7+7=47+7

x=54

Step-by-step explanation:

x=54

Step-by-step explanation:

since the angle is 90°, simply subtract 90 by 43 to get 47. However, in order for the angle above to equal 47, add 7 to the answer to get 54.

to check the answer, plug in x.

if it works properly, 54-7 should equal 47 and 43+47 should be equal to 90.

I hope this helps you!

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
