If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
5x - 11 = 24 5x = 35 x = 7
steps: 3(5x-7) =(3)(5x-7) =(3)(5x)+(3)(-7) answer: 15x-21
5x - 7 = 23 .....+7....+7 5x=30 --- --- 5.....5 --->(x=6)<---
The GCF of 7 and 14 is 7.
3x-28-5x=5x+13 Let us first solve the variables -2x-28=5x+13 Transposing -28 to Right hand side -2x=5x+13+28 -2x=5x+41 Transposing 5x to left hand side -2x-5x=41 -7x=41 equation 1 x=41/-7 x=-41/7 Hence the required answer is -41/7. You can verify it by substituting the value of x in the given equation. If Right hand side is equal to Left hand side the answer is right. Let us verify Substituting the value of x=-41/7 in the given equation1 -7(-41/7)=41 -7 X -41/7 =41 41=41 LHS=RHS Hence Verified
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
5x+30=7x 7x-5x=-30 2x=-30 x=-15
5x-7 is an algebraic expression
what is |5x-1|+7=3x
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
