X=3 . ok well ur gonna do reverse mathematics so start by subtracting 2 from 17 (bc the oppistite of addition is subtraction) an then rewrite the equation. 5x=15 and then divide 15 by 5 and it equals 3 and then do it all over again meaning put the equation as it was but with the value. 5x3+2=17 and it all makes sense. im so sorry i answered so late i just got this question recommended to me.
M + 5n = 7
subtract 5n from each side
m = -5n + 7
Check the picture below.
make sure your calculator is in Degree mode.
but will run you about 36.8698976458° and 53.13010235415598°.
The answer to the question is B
Answer:
x=1
Step-by-step explanation:
We wanna have the same amount on both sides
There are 3 circles on the left and 7 circles on the right. There are also 4 triangles. Turn into numbers...
4x+3=7
4x=7-3
x=1
We can check by substituting one
7=7
