What is the solution to equation x- 7 4?
[ x = 11 ] is.
What is the definition of solution of equation?
An algebraic equation has (at least one) variable, usually called x. To solve the equation means to figure out the value of x. For example, in the equation x + 4 = 7 the solution is x = 3, because 3 + 4 = 7.
What is the solution to the equation x - 7 equals -4?
11
What is x in this equation negative 9 minus 7 times x equals negative 5?
If the equation is (-9-7)x = -5, then x= .3125 or 5/16 If the equation is -9-7x = -5, then x = -.571428 or -4/7
What does 2x plus 5y equal 4 and x plus 5y equal 7?
Is this a system of equations? 2X + 5Y = 4 X + 5Y = 7 solve for X using bottom equation X = 5Y - 7 insert into top equation 2(5Y - 7) + 5Y = 4 distribute 10Y - 14 + 5Y = 4 solve for Y 15Y = 18 Y = 18/15 = 6/5 use bottom equation to find X X +5(6/5) = 7 X = 1 check with bottom equation 1 + 5(6/5) = 7 7 = 7 not true for top equation ( sorry, I forgot what happens then-resubmit question )
