Answer:

Step-by-step explanation:

What you are being told is that 3x - 7 is twice as big as x. You can see that because ST (for example) is cut into 2 equal parts. So is UT (cut into two equal parts). So the parts of the Big Triangle (SUT) are twice as Big as the parts of the small triangle DET

So multiply x by 2

3x - 7 = 2x                                Add 7 to both sides

3x - 7  + 7 = 2x + 7

3x = 2x + 7                               Subtract 2x from both sides

3x-2x = 7

x = 7
