Answer: 1250
Step-by-step explanation:
Let x be the cost before vat
13/100x = 162.50
x = 162.50 x 100/13
x = 162.50 / 2.13
x = 1250
Answer:
-65 is answer if we will solve it then it will be answer
Answer:
x=2
Step-by-step explanation:
7x - 3 = 11
Add 3 to each side
7x - 3+3 = 11+3
7x = 14
Divide by 7
7x/7 = 14/7
x = 2
Step-by-step explanation:
1) 2x+3y-3y=1-3y. -x+2y= -4
2x/2=1-3y/2. -(1-3y/2)=-4
x=1-3y/2. -1+3y/2= -4
x=1-3(-2)/2 3y/2= -4+1
x=1+6/2 3y/2×2/3= -3×2/3
x=7/2 y= -2
S.s{ 7/3,-2}
2). -4x-6y+6y=7-6y. 4x+y= -2
-4x/-4=7-6y/-4. 4(-7-6y/4)+y= -2
x= -7-6y/4. -7-6y+y = -2
x= -7-6/4 -5y/5= 5/5
x=-13/4 y= 1
S.s { -13/4, 1 }
