To solve for x,

4.7x = 2.5x + 8.8
minus 2.5x from both sides:
2.2x = 8.8
divide both sides by 2.2:
2.2x/2.2 = 8.8/2.2
simplify:
x = 4

Answer is 4
#1 subtract the 2.5x and bring it to the other side (4.7x-2.5x=2.2x)
#2 then to get x by itself you divide both sides by 2.2 (2.2x=8.8/2.2)
#3 you get x by itself (x=4)

Type the numerical answer ONLY. (no spaces)

Fantom [35]

Answer:

Step-by-step explanation:

Mathematically, when we add all the angles of a triangle, we get 180

Thus;

x + 1 + 2x-2+ 3x-5 = 180

6x-6 = 180

6x = 186

x = 186/6

x = 31

so the measure of the biggest angle is 3x -5

= 3(31) + 5 = 93 + 5 = 98
