Answer:
1.
-2 = x/4 + 1
Subtract 1 from both sides:
-2 - 1 = x/4 + 1 - 1
-3 = x/4
Multiply both sides by 4:
-3 * 4 = x/4 * 4
-12 = x
2.
3x+5
3.
X= 12 or 18
This could be read two different ways.
0=2/3x-12
12=2/3x
12÷2/3=x
12*3/2=x
18=x
—-OR—-
0=2/3(x-12)
0=2/3x-8
8=2/3x
8÷2/3=x
8*3/2=x
12=x
270 = 54 x 4 Hope you have great day!
Answer:
x= 35
Step-by-step explanation:
Cos x = Sin( 20+x)
Sin ( 90 – x) = Sin(20+x)
90 – x = 20+x
2x = 70
x = 35
