y=x4−7; y=2

Y=2 (2)=x.4-7

2+4x-7

4x-7=2  get the variable alone by doing the same thing to both sides

4x=9

4x/4=9/4

y=9/4

x=9/4

Solve for x. 1/2x + 3 = 2/3x + 1
makvit [3.9K]

Answer:

x = 12

Step-by-step explanation:

\frac{1}{2} x + 3 = \frac{2}{3} x + 1

multiply through by 6 ( the LCM of 2 and 3 ) to clear the fractions

3x + 18 = 4x + 6 ( subtract 3x from both sides )

18 = x + 6 ( subtract 6 from both sides )

12 = x

Ouch! That is hard but I can do it. First, find the area of the triangle. (for both is 60) Then find the area of the rectangle (base) which is 48. Then do the rectangles on the sides which are 72 each (for both is 144) Then add it all together and get 252 ft squared or cubed.

What is 3.3(x-8)-x=1.2
11Alexandr11 [23.1K]
Multiply 3.3 by everything in the parenthesis.

3.3x - 26.4 - x = 1.2

Combine like terms.

2.3x - 26.4 = 1.2

Add 26.4 to both sides.

2.3x = 27.6

Divide 2.3 on both sides.

x = 12

Hope this helps!
