3/4x=15 you flip 3/4 to 4/3 and cancel it out on one side leaving x by itself then you multiply 4/3 by 15 and you get 60/3 and that equals 20 x=20
Answer:
x-3
Step-by-step explanation:
(x^2-9)(x^2-9)/x^2*(x+3)+9(x+3)
(x+3)*(x^2+9)/(x+3)*(x^2+9) cross multiply
(x^2+9)*(x+3)/(x^2+9) cross multiply
x+3 final anser
<span>m∠CED = </span><span>1/2(m∠AOB + </span><span><span>m∠COD)</span> = 1/2(90° + 16°) = 1/2(106°) = 53°</span>
First one simplifies to 2x + 6 = 2x + 7 which can't be true so this one has No Solution.
Same applies to the second equation ( 5x + 15 = 5x - 15) No solution
also the last one has no solution because it simplifies to 4x + 20 = 4x + 19
