Answer:
-1.596
Step-by-step explanation:
Apply log base 4 both sides
log4(4^(x+3)) = log4(7)
(x+3)log4(4) = lg7/lg4
x+3 = 1.403677461
x = -1.596322539

Answer: first one 5.55
Step-by-step explanation:
-4x+8=42
-4x+8-8=42-8
-4x=34
-4x=34
-4x/-4=34/-4
x= - 17/3
(2x+1)+89=180. 180 is the angle of a straight line. Set your two known sides equal to 180 and solve for x if needed.
