Who can help me solve the equation 7.2 × = 64.8 0.5 × + 11.4 = 19.4 × / 7.6 = 41.8

Who can help me solve the equation 7.2 × = 64.8 0.5 × + 11.4 = 19.4 × / 7.6 = 41.8

7.2X=64.8
X=64.8/7.2=9
0.5X+11.4=19.4
0.5X=19.4-11.4=8
X=8/0.5=16
X÷7.6=41.8
X/7.6=41.8
X=41.8*7.6=317.68

We solved the equation X-2 = x (X-2) by 3Q

x-2=x(x-2) x(x-2)-(x-2)=0 (x-2)(x-1)=0 x=2..x=1

Solve the equation 3Q & # 179; - 3Q & # 178; + 3q-2 = 0
The solution equation should be 2q & # 179; - 3Q & # 178; + 3q-2 = 0

2q & # 179; - 3Q & # 178; + 3q-2 = 2 (Q & # 179; - 1) - 3Q (Q-1) = 2 (Q-1) (Q & # 178; + Q + 1) - 3Q (Q-1) = (Q-1) (2q & # 178; - Q + 2) = (Q-1) [2 (Q-1 / 4) & # 178; + 2-1 / 8] = 0 ∵ [2 (Q-1 / 4) & # 178; + 2-1 / 8] > 0 ∵ so: q = 1

X + 75% x = 14. How to solve this equation?

x+0.75x=14
1.75x=14
x=14/1.75
x=8
