Step-by-step explanation:
6x = 12
Get x by itself.
Step-by-step explanation:
If this is just for gaining points stop doing it. By the way 13 is bigger -8.
Answer:
no solution
Step-by-step explanation:
-5x + x + 9 = -4x + 12 [combine like terms]
-4x + 9 = -4x +12 add 4x to both sides]
9=12 is no solution
Answer:
x = 4 , y = 2
Step-by-step explanation:
Using the sine / tangent ratios in the right triangle and the exact values
sin60° = and tan60° = , then
sin60° = = = ( cross- multiply )
x = 4 ( divide both sides by )
x = 4
and
tan60° = = = ( multiply both sides by y )
y = 2 ( divide both sides by )
y = 2
A negative plus a negative equals a negative.
