-4 + 2y = 242y + 4 = 242y + 4 - 4 = 24 - 42y + 4 - 4 = 24 - 42y = 24 - 42y = 202y/2 = 20/22y/2 = 20/2y = 20/2y = 10Therefore the y-intercept is at (0,10) or has a value of 10
It does not, this equation is false.
2y + 3 = 42y = 4 - 32y = 1divide both sides of the equation by 22y/2 = 1/2y = 1/2 in fractionory = 0.50 in decimal
10
That is not a correct equation. The numbers on the left equal -16, not 0. This is an equation with no solution.
1 + 1 = 2
In the equation 3x plus 7 equals 13, x is equal to 2.
r = 4
No. It is a meaningless equation. You may have intended to say: 2 times the sum of x and g is equal to 2x plus 2g.
whats w stand for? -7w + 3(w+2)= -14
(-3,-4)
if the question u are asking is something like this 1/2 - ( - 1/2 ) then the answer is simple all you have to do is solve the equation like this 1/2 - ( - 1/2 ) = 1/2 + 1/2 = 2/2 = 1 its the - (-1/2) that is important remember the rule minus and minus equal plus plus and plus equal plus minus and plus equal minus remember and i hope it helps :)
