Subtract 1 form both sides of the equation
Double first equation: 2x + 2y = 4 Subtract this from second equation giving 5y = 5 so y = 1 and x = 1
Solving the equation for "y" gives you the slope-intercept form.
the value of
Solving tne simultaneous equation gives x = 19.8 and y = -2.2
-2
the first step in solving the equation is to subtract the nine from the three. you will get negative 6.
Solving for d: d = -4.7 satisfies the equation.
There are 2 unknowns
Double first equation: 2x + 2y = 4 Subtract this from second equation giving 5y = 5 so y = 1 and x = 1
Solving the equation for "y" gives you the slope-intercept form.
the value of
Solving tne simultaneous equation gives x = 19.8 and y = -2.2
88=13+5x -13 -13 75= 5x 75/5 =15 x=15
-2
It can't be solved because its discriminant is less than zero
x = 2 or x = 2/5
Multiply the first equation by -3
